IEEE 802.11 Wireless LAN PHY Layer (RF) Operation and Measurement
The use of wired Local Area Networks has become ever more commonplace, even in situations where only a few computers need to be connected together. Price reductions have helped stimulate use and so have easier system configuration and increasing robustness.
A number of applications can benefit from the removal of the cable connections needed by a fixed LAN. Remote database access is a good example—from warehouses to retail stores to college campuses. WLAN cards will also be used soon for public Internet access in certain “hotspots,” such as airports and hotels, where users are largely stationary and need access to a variety of medium- and high-speed digital services.
This application note is written for those who desire an understanding of the test system configuration and testing of Wireless LAN (WLAN) devices and some of the issues that arise in connection with it.
